Benefits of technology

The patent is about a system that improves the performance of cook stoves by controlling the air flow. This system helps to burn solid fuels better, resulting in higher thermal efficiency, lower levels of particulate matter, and lower levels of carbon monoxide.

Problems solved by technology

These fuels are frequently burned using indoor cook stoves, which release smoke and other harmful compounds (e.g., carbon monoxide).
This can be a significant health and safety hazard, causing illness and premature death in populations that have few cooking or heating alternatives.

Performance Comparison in Cook Stove With and Without Air Flow Control System

[0138]This example compares the effect of using an air flow control system in a cook stove, with respect to fuel use, cooking power and emissions of the stove.

[0139]A wood stove was used in this example. The setup of the cook stove and air flow control system is depicted in FIGS. 8A-8E. A flat bottom pot was used in all tests. The pot dimensions were 24 cm in diameter, and 16 cm in height. The stove was first tested without the use of the air flow control system (Stove 1; Tests 1, 2, 3). The stove was tested again without the use of the air flow control system, but the stove was modified to operate in the natural draft operating mode, which included using a smaller diameter riser tube and shorter pot supports (Stove 2; Tests 4, 5, 6). The stove was then tested with the air flow control system in the forced draft mode (Stove 3; Tests 7, 8, 9), where the air flow rate was approximately 0.17 m3 / min and the air...

Abstract

Air flow control systems for use in the combustion of solid fuel are provided. Such air flow control systems may be used in a combustion apparatus, such as a cook stove. The use of such air flow control systems in the combustion apparatus can efficiently combust solid fuels with low emission of particulate matter and harmful gases.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to U.S. Provisional Patent Application No. 62 / 834,262, filed Apr. 15, 2019, which is incorporated herein by reference in its entirety.FIELD[0002]The present disclosure relates generally to combustion of solid fuels, and more specifically to an air flow control system suitable for use with cook stoves to improve combustion of solid fuels.BACKGROUND[0003]A large portion of the world's population relies on solid fuels for cooking, such as collected woody sticks. These fuels are frequently burned using indoor cook stoves, which release smoke and other harmful compounds (e.g., carbon monoxide). This can be a significant health and safety hazard, causing illness and premature death in populations that have few cooking or heating alternatives. Thus, there is a need for cook stoves which can burn solid fuels such as biomass with lower emission of particulate matter and harmful gases.BRIEF SUMMARY[0004]The present d...
